Comment(by simonmar):

 I'm completely confused about what this ticket is asking for.  Could
 somebody explain in more detail please?  e.g. the ticket seems to be
 asking for something in the `Data.Dynamic` library, but then there's lots
 of talk about something in the GHC API.  What is `TypedAny`?
